The evaporator coil is probably frozen too.The fan might of failed and it caused the evaporator coil to freeze along with the suction line. Based on what you said about hearing a noisy blower motor noise. I believe the blower motor failed and caused your problem.There's only a few things that cause freezing; 1. blocked or no airflow 2. low or loss of refrigerant. You have no airflow, most likely because of a defective blower motor.

From any HVAC supply house.

The bearings may be worn a little in the motor. This will cause a little bit of a whining sound when the unit is running. Eventually, (if this is the problem) the motor will quit and you will have to have a new motor.
Also, make sure the outdoor coil is clean. This coil is behind the fins that are on 3 sides of the unit. You can wash this coil out with a hose and sprayer. First, disconnect power before servicing. Mark

Hi,

Here is a tip that I wrote about how to clean your condenser

Cleaning Air Conditioner Condenser Coil with Pictures

Hello, in order to remove the coil it will require some work, you need to cut into the plenum first then either pump down the refrigerant into the condenser or recover the refrigerant. Then cut the line set close to the coil to remove the coil. If you are familiar with hvac work then it is pretty simple, however if you are not to familiar with it I would call a hvac to do the work.

Turning on the cooling starts with the thermostat, turn the thermostat to the cooling setting, and then set the temp. setting down below the room temp.
That is the basics,,
If you have more advanced problems, please just get back to me and I can help you work thru some more advanced solutions.
Have a Great Day!

service once a year clean dirt and hose the coil out make sure power to outdoor unit is off also make sure you keep a new air filter change about every 2 months you should also have a tech test you pressures this could cause poor cooling also need to clean inside coil also a service tech will probaly need to do this good luck

Are you asking what indoor coil size you need to match your outdoor unit? If so the model number of the outdoor unit will have a number divisible by 12. example an 036 is a 3Ton a-c an o42 is a 3 1/2 Ton. Probably the numbers right after UAMB.
